COMBINED SAND AND WATER TRAP.

' Application tied october 25119211. seriai No. 510,343.

To all who/m t may concern:

Be it known that we, ROBERT J. Maliens and HARRY ANDERSON, citizens of the United States, and residents of Coalinga, in the county of Fresno, State of California, lhave invented certain new and useful Improvements in CombinedSand and VaterTraps, of which the following is a specification.

Our invention relates to a combined sand and water trapA for use in oil wells and the :object thereof is to produce a trap of that character which will automatically separate the sand and waterfrom the oil as the saine is pumped from the Well. f

Another object is to produce a device of the above character which can be easily and quickly cleansed of the sand and water .at

the will of the operator.

"A still further object is to provide means in aV device of the a-bove character for indicating the amount of water contained there inV visually and to provide means for easily and quickly iiushing the sand therefrom.

Other objects and advantages will appear hereinafter and, while we have shown and will describe the preferred form of our in'- vention, it will be understood that we do not limit ourselves to Vsuch preferred form but that various changesand adaptations may -be made therein without departing from the spirit of our invention. Y

In the drawings acompanying and form- Fig.r l is a side elevation of in its position of use.

Fig..2 is a central vertical section through our invention the trap;

Fig'. 3 is a .top plan of Fig.' 2. Referring to the drawings 'our invention comprises an outer tubular casing `or drum 5 closed at the `top by a cover 6 removably secured thereto by bolts 7, and being 'supported at a suitable distance abover the ground by a foundation 8. Mounted cenn thereof, is provided a b'leeder valve 25 by trally of the bottom 9Iof casing 5, preferably integral therewith,is a funnel 10`which projects a` distance fromeach side of said bottom 9 and upon the lower` smallerfen'd of said funnel is mounted a ,valve 'or shut off cock 11 by means of which they outlet from said funnel is* controlled. Theiupper end of said funnel exte'nd's'fupwardly and youtwardly'and terminatesn at a point toprovide a narrow concentricspace between it andthe sides of said casing.y Bividing casing lvverti'cally isa pa-rtition'12, whiclifex" theY casing 5.

tends from a point a short distance above the upper termination of funnel 10 to a point near the top of said casing 5, and extending from one side of said partition to Vthe opposed wall ofv casing 5 are baffles 13,

14 and 15. Battles 18, 14 and 15 are proi vided with openings l16, 17 and 18 therethrough through which the oil is permitted to flow on its passage out of the trap. It will be noticed that battles 13, 14 and 15 are mounted angularly to the partition and wall of the casing and that the openings therein are at the lower termination thereof the purpose. of which will be hereafter explained, and that we have lshown three baflies but we wish it understood that more or less of said baffles may be used if desired. Extending from the side of casing 5 just above the upper termination of the uppermost baifle is a pipe 19 which communicates with the interior of said casing and conducts the oil therefrom to its place of storage. Projecting through the side of casing 5 on the opposite side of the partition 12 to the ba'ies 13,A 14 and 15, is a `supply pipe 20 the inner end of. which is bent to extend downwardlyI and is secured to said partition centrally of said casing 5, The `other end of saidV sup ply 'pipe 20 is connected to a source of supply, not shown. Extending through the a pipe 21 the inner end of which is bent to extend downwardly and is secured to said partition centrally ofthe casing 5. c

The outer end of ipe 21 has mounted side of casing 5 parallel with partition 12 is thereon a shut ofia coc 22 which cock is in turn connected by a pipe23 to a water supply, not shown, and provides means for flushing out the sand in funnel 10 when desired. Mounted inthe side of casing 5 near the lower end thereof4 is a gage glass 24 'i which indicates the heightof the water in In the 'bottom 9 of casing, near the edge means of which the water in casing 5 may be permitted to escape. l e

In the operation of our trap oil will enter the casing 5 through the supplypipe 20, it

Voil rises within'gsaid casing it will flow upwardly through the o enings 16, 17 and 18` in baffles 13, 14 an 15 and thence` out through ypipe. 19 to its place ,of use or storage. As the oil .flows into the casing the sand contained therein; being of greater spe citic gravity Athan the oil and water; will fall to lthel bottom of said funnel and as the oil flows over the top of the Vfunnel the water contained therein, being of greater specific gravity than the oil, will settle at the bottom of casing 5 from whence it is drawn by the bleeder valve when the gage glass indicates the necessity therefor. As the oil flows npwardly through the openings in the baliies anysand still carried ibythe oil will fall upon said battles and; by yreason of `the angular inclination thereof `will slide down the same into the funnel. lVhen it is desired to remove the accumulated sand in the funnel, valve 1l is opened at the tbottom of said funnel, and valve 22 is also opened permitting a stream of Water to flow upon said sand and funnel and Hush ythe saine out'through opening cock 11.
